I can guarantee it is not region free for DVD's, I have a Malata DVP 520D DVD player that I use to play PAL and non-region 1 DVDs. I stuck a Pal DVD into the PS3 and it wouldn't play it, it hated my disc.....
Anyways, if you can figure out some way to get it to work that would be great, then I could up convert them and I wouldn't need my Malata anymore....
FYI-> I'm using a 60GB Model
